Whether you're aiming for a big, bouncy style full of volume or a smoother look with subtle curls, using the right round brush is crucial. These thermoceramic round brushes are ventilated to evenly distribute and retain heat when used with a hairdryer. When heated, the ceramic barrel retains heat and smooths the hair while preventing frizz and flyaways. Beautifully crafted with uniquely textured, biodegradable PLA handles, flexible PCR bristles that grip the hair perfectly without pulling, and thermoceramic, recycled aluminum cores, they are excellent for styling hair while also contributing to environmental protection. The medium size is perfect for medium to short hair to create medium waves, add volume, style the bangs, and speed up hair drying. The product is PETAcertified crueltyfree and vegan.
